The iMac "Core i5" 1.6 21.5-Inch Aluminum (Late 2015/Broadwell) features a 14-nm "Broadwell" 1.6 GHz Intel "Core i5" processor (5250U) with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 8 GB of onboard 1867 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of order, but cannot be upgraded after system purchase at all), a 1 TB (5400 RPM) hard drive, and an "integrated" Intel HD Graphics 6000 graphics processor that shares system memory. It also has a built-in "FaceTime HD" webcam and stereo speakers. I am swapping out this Mac for a PC, so this is no longer needed. Works great. Will factory reset all data that is stored in here before shipping it out. Great condition, NO damage. Firm on price. Need gone.
